BAND GUTTER AND FEEDER Specification of Letters Patent.

Patented Nov. 27, 1906.

Application fil d October 6. 1905. Serial No. 281,659.

To all whom it may concern:

Be it known that I, PET R B. JANTZ, a citizen of the United States, residing at Galva, in the county of McPherson and State of 'Kansas, have invented a new and useful certain new and useful improvements whereby the bands are promptly and eifectually cut and the straw is regularly and evenly fed to the threshing-cylinder in a simple and entirely satisfactory manner. 3

A further object of the invention is to provide for the'verticaladjustment of a portion of the carrier-floor so as to accommodate the device to the condition of the Wheat, and thereby prevent choking of the machine.

it is proposed to have the retarders carried by the adjustable floorportion and to efiect the stripping ofthe straw from the retarders, so as to prevent the latter from becoming choked by accumulations of straw thereon.

A still further object of the invention is to provide for the'convenient vertical adjustment of the inner ends of the cutter-bars and also to give the latter a novel form for the purpose of preventing choking of the feeder at the lowermost limits of the bars. 7

/Vith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particulariy pointed out in the appended claims, it

being understood that changes in the form, proportion, size, and minor details may be made Within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

in the accompanying drawings, Figure 1 is a longitudinal sectional view of\a band-cutter and feeder embodying the features of the present invention in its operative relation with respect to a threshing-machine. Fig. 2 is an enlarged sectional view on the line 2 2 of Fig. 1. Fig. 3 is an enlarged fragmentary plan view of the adjustable floor portion of the feeder.

Like characters of'reference designate corresponding parts in each and every figure of the drawings.

As embodied in the accompanying drawings, it will be seen that the frame 1 is of conventional form and is fitted to the frame 2 of the threshing-machine in the usual or any preferrcd manner. The frame of the threshing-machine has been broken away to show the threshing-cylinder 3 and the usual concave 4. Within the front portion of the frame 1 is the stationary upwardly and in-' wardly inclined floor portion 5, in rear of which is a vertically-adjustable fioor portion made up of overlapped metallic plates 6 and v -7. The plate member 6 is provided at each side with a side bar 8 which is pierced at its upper end by a transverse shaft 9, the upper extremity of the side bar being bifurcated, as at 10, for the reception of a pulley or sprocket-wheel 11, carried by the shaft 9.

Each side of the other floor member 7 is provided with a side bar 12, which overlaps the bar 8 upon its inner side and is provided with a longitudinal slot 13, in which is received the headed fastenings i i, preferably bolts, carried by the side bar 8, thereby to efiect adjustment of the section 7 back and forth across the section or member 6. A transverse shaft :15 pierces the lower or outer ends of the side bars 12, in which said shaft is journaled, the ends of the shaft being terminated short of the sides of the frame in order that the shaft ma be adjusted with the floor-section 7. I T e shaft 9 in addition to piercing the side bars 8 also passes through or is supported upon the side walls of the main frame 1 and constitutes a pivotal support for the adjustable floor portion 6, adapted to be swung vertically, as will be hereinafter described. Upon the shaft 15 there is a series of retarders 16, fixed to the shaft so as to rotate therewith and regularly spaced by means of spacing-sleeves 17', as best shown in Fig. 3 of the drawings. To accommodate the retarders, the lower edge of the floor-section 7 is provided with a series of bifurcations 18, which produce stripping-fingers between the retarders for the purpose of stripping therefrom such straw as may tend to wind around the retarder-shaft, whereby said retarder-shaft and retarders are cleared of any accumulation of straw, and thus prevented from becoming choked.

For the purpose of raising and lowering the adjustable floor portion of the feeder a rockbar 19 is mounted transversely across the upper portion of the frame 1 in substantial vertical alinement with the retarder-shaft 15. Upon each end portion of this rock bar and wlthin the main frame there is a crankearm 20, from which depends a link 21, having its lower end connected to the adjacent sidevbar of the adjustable floor portion. One end of the rock-bar is extended externally of .the frame 1 and provided with a ratchet-wheel 22 and .a crank-handle 23, there being a pawl or dog 24 mounted upon the frame in cooperative relation with the ratchet-wheel, so as to hold 'the'rock-barin" any adjust-ed position. "By manipulation bf the crankhandle'23 the lower free end "of the adjustable floor portion may beraised and lowered so as to accommodate the device to the condition of thematerial under treatment.

The advantage of having the retarder' carried bythe adjustablefloor portion independent of the-sides 'ofitheframe is that-such arrangement avoids the formation of openings in the frame, through which the material under treatment may escape.

Moreover, by having the. .reta rder' supported solely upon the adjustable floor portion. there are no guideways liable to become choked, and thus interfere with the convenient adjustment of the floor portion.

The bundles orsheaves'of wheat are delivored to the feeder by means of an endless conveyor 25,- preferably including-s rocket- :ehains and slats or cross b'ars Qtiyeac of sa d chains running overthe adjacent pulley .or sprocket. 11 on the shaft 9 and a similar sprocket or pulley '27 upon the retaTdershaft 15, whereby the latter is driven di rectly by the conveyer, thereby dispensing with additional driving means for the re tarder. Directly beneath the shaft 9 there is another shaft 28,"whieh pierces one side oi theframe 1 and is provided nponits ou'ter nd with a drive-pulley; 29, "there being a spree-retwheel 30 'upon the shaft '28" for each the conveyor-chains 25, whereby the oonveyer is driven from the shaft 28 "and. the latter is driven through the medium of the p'l'il-leyfit). The front portion of the conveyer125 is carried by a supplemental frame portion 31. which hin ed at'its forward end and upon its nnder si e to the rear end of the main frame 1, as shownat 32, in orderthat the conveyer may be foldedba'clr beneath the frame whennot in use.

With the feeder supported in connection with'a threshing-machine, as shown in Fig. 1 of the dra s, power is taken from a pulley upon one en of the shaft of the threshing-v cylinder by means of .a belt 52, which engages a pulley. 53 upon one endof the driveshaft 41 of the band cutting mechanism.

Another pulley 54 is provided upon the, driveshaft 41, and from this pulley a belt 55 extends to the pulley 29 upon the'shaft 28 for the urpose of driving theconveyer 25.

, hen the apparatus is in operation, the bundles or sheaves of wheat are deposited upon theconveyer and are thereby carried forwardly into the rear portion of the feeder, where the bands are severed by the action of the blades upon the rear portions of the cutter-bars, thewheat of course being carried onward by the conveyer and spread out into acomparatively thin layer by the action of the rear series of teeth. It will here be eX- plained that the band-cutti-ng'devices operatuponthe top of the wheat work much faster than the retarders which operate upon the under side of the wheat, whereby the forward series of teeth of the band-cutters are tearing off and feeding the upper portion of the wheat to the threshing-cylinder instead cylinder, this adjustment being more the straw be dry and more easily distributed,

as in headed grain, the cutter-bars can be raised and the retarder lowered, thus admitting of a free flow of straw to the threshingaccomplished while in operation.

Having fully desc -'bed the invention, what is claimed isv v 1.- A band-cutter and feeder having overlapped fioor-sections,\0ne of the sections being pivotally supported, the other section being slidably ad'ustable upon the pivotal section and provi ed in its free end'with a series of bifurcations, a series of rotatable retarders carried by the slidable section and working in the respective bifurcationaand means to adj ustably swing the sections as a whole upon the pivotal support ofthe pivoted section.

2. In a band-cutter and feeder, the combination with a frame, of a vertically-tiltable floorsection provided at its forward end with a series of bifurcations, a shaft carried by-the front portion of said floor-section, rotary retarders carried by the shaft and working in the bifurcations, the floor portions between the bifurcations constituting strippers for the retarders, pulleys upon the shaft, and

an endless feed-convr'ziyer embracing the tiltable floor-section an engaging the pulleys upon the shaft for actuating the retarders.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
